Laying Low as the Dark Lord at Hogwarts

A Dark Magic experiment splits Annal Fortesmos's soul in two, creating Annal and the spirit cat Fortes. From then on, they gain the ability to see the echoes of Ancient Magic. Hoping to obtain Ancient Magic and study Horcruxes to solve his soul problems, Annal Fortesmos accepts Dumbledore's invitation and returns to his beloved Hogwarts. Annal: Dumbledore, I may have grown up in an orphanage, graduated from Slytherin, and split my soul in a Dark Magic experiment... but you know I'm a good person. P.S.
